Directional Sound Speaker, Ultrasonic Parametric Speaker Model X2, Portable Directional Audio Loudspeaker for Museum, Showroon, Digital Signage and More

I had high hopes for this product. My wife had a head injury so now the only way I can listen to music or the TV is with my AirPods. While they work fine, sometimes it is nice to not have to use them.I read the entire manual - obviously machine translated and found no mention of how to connect with Bluetooth. Fortunately, once I powered them up, they showed up on my phone and connected without any issue. This earned them one star.That is as good as it gets!Once I started playing music, it was obvious that you could hear the music no matter how the speaker was oriented relative to the listener. The volume did increase when it was pointed directly at you, but there wasn’t a huge difference. And, adjustments to the output volume on my phone made little difference to the volume coming from the speaker.From the time I connected and tried them out to the time I had them back in the box and ready for return shipment was less than 10 minutes. It was so obvious that their claims fell way short of reality. Don’t waste your time or money on this product. In my case, I am back to AirPods.A side note, I know the inventor of this technology. He lives close by and is brilliant, which is why I was excited to see it in an “affordable” product. However, this product clearly doesn’t utilize the technology that is available.
